Kim Kardashian shares touching video tribute to her father on anniversary of his death

All the feels. It was 13 years ago that Robert Kardashian Sr. passed away. On Friday, his daughter Kim Kardashian West posted a touching video to honor him.

"Our dad passed away 13 years ago today and we miss him every single day but today we wanted to share with you a glimpse of who he was," she wrote on her subscription-based website and app. "It was hard to find footage of our dad since he loved to film us and was always behind the camera but here's a little look into who he was to us."

Robert, who was married to Kris Jenner before she remarried Bruce Jenner, died in 2003 from esophageal cancer. He was 59.

"OK, this is my dad," one of the Kardashian brood says off camera as a montage of video clips begins playing. The video shows Kim, Kourtney, Khloe and Rob Kardashian all as youngsters. Other moments captured on camera include him at a baptism and at his wedding to Kris.

To his kids, Robert was simply dad. To the public, though, he was largely known as one of OJ Simpson's lawyers, being a part of the often-described "Dream Team" that represented the athlete during his murder trial in the deaths of ex-wife Nicole Brown Simpson (one of Kris' best friends) and her friend Ron Goldman.

"Happy Birthday dad! So much has gone on in our lives since you've been gone, and I know you have been my guardian angel seeing it all unfold!" Kim wrote alongside a photo of her dad. "I love you and miss you so much!"
